In the years since the Flint water crisis began, the Michigan city is still grappling with the aftermath. Many have gotten involved and stepped up to offer support, including some of the community's youngest members. For the final episode in our series of conversations with youth leaders, Pete talks to our youngest guest yet: Mari Copeny, also known as Little Miss Flint, is a 13-year-old water rights activist who rose to international fame when, at age 8, she fought to help her hometown by organizing a mass bottled water drive. To date, she has donated over one million bottles of water and raised over $500,000 for school supplies for Flint-area families affected by the contaminated water.
